Abstract: A lumber dry kiln consists of one or more chambers designed to provide and control the environmental conditions of heat, humidity, and air circulation necessary for the proper drying of wood. As the development of the modern dry kiln has progressed, a number of design modifications have been explored in relation to the mechanism of heat supply, arrangement and type of fans, control of relative humidity or wet-bulb temperature, and use of various materials for construction of the chamber. The design of a kiln has an important bearing on its operation and drying efficiency. A properly designed and operated kiln will dry most species of lumber or other wood products to any specified moisture content between 3 and 19 percent in a reasonably short time without appreciable losses caused by drying defects.
